SPINDLE AND BOLSTER THEREFOR.

SPECIFICATION forming part of Letters 'Patent No. 241,632, dated May 17, 1881.4 'Appncatin inea December is, 1ste. (No model.)

To all whom it may concern:

Be it known that we, JOSEPH DUFFY and HENRY WHoRwELL, of Paterson, in the county of Passaic and State of New J erscy, have'invented a new and Improved Spindle and Bolster Therefor, of which the following is a specification. v

The object of our invention is to provide a new andimproved spindle and bolster, in which the spindle is firmly supported, and, with its attached whirl, can be conveniently detached from the bolster when required, the spindle being constructed with oilchambers that greatly facilitate the lubrication of the spindlebearings. In the accompanying drawings, Figure l is a front elevation ot' an improved spindle and bolster. Fig. 2 is avertical sectional elevation of the same. Fig. 3 is a horizontal sectional view of the same on the linerrl m, Fig. 2. Fig. 4 is a plan view of the upper bearing of the spindle.

Similar letters of reference indicate corresponding parts. i

' The bolster is formed of two detachable parts, namely, the tubular socket`A, for receiving the lower end of the spindle B, and the clamp-ringO, provided with an upright brack- 'et-arm, D, h`olding the tubular bearing E of the spindle in its upper end. The tubular part or socket A ot' the bolster is provided at its upper end with an annular flange, F, forming a shoulder resting on the railv-G, through an aperture of which the tubular part ,A.of the bolsteris passed and is locked in position on this rail G by a binding-screw, H. This annular flange F is provided with a horizontal groove, J, in its cylinder-surface, and a recess or notch', K, extends from this groove to the upper edge of this flange F.

The clamp-ring O is provided with a screw, L, by means `of which it can be contracted or liberated to enlarge itself. The inner diam eter of thering C is practically equal to the outer diameter of the annular flange F, and a short stud, M, projects from the inner surface of the ring C, and is of :such size as to fit into the notch K and the groove J.

A whirl, N, is mounted on the spindle B, and has a sleeve, O, attached to its upper surface of sufficient size to surround the tubular bearing E of the spindle, and extending up to the under side of the annular upper end, D', of the arm D. The tubular bearing E extends from the recessed top of the annular upper end, D', of the arm D,`fforming the oil-cup Q, down to the upper surface ofthe whirl, and, as has been stated, is surrounded by the sleeve O.. The upper edge of thecbearing E is provided with one or more notches, a a, for permitting the oil to pass from the cup Q in between the bearin g and the spindle. The lower end of the spindle rests in a bearing, P, which is inserted in the ltubular socket or part A, and can be removed when worn out and replaced by another.

The operation is as follows: The tubular part A rests on the rail G, in the manner shown. If thespindle B is to be removed the screw L is loosened and the ring C is turned until the stud M, which rests in the groove J, is opposite to the notch K, upon which the ring and spindle are raised, the stud M passing through the notch K. The spindle is replacedin a similar manner and the ring C is drawn'up tight again. The oil that passes from the cup Q down through the bearing E into the oil-cup `formed by the sleeve O will be forced upward on the spindle again by the revolutions of the latter, and as the sleeve extends up to the lower edge of the upper part, D', of the arm D none of the oil will or can be thrown outward by the centrifugal force, and the oil will circulate in the bearing E until it has evaporated, or has been decomposed by the heat.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- The combination, with the rail G, of the tubular part A, provided with the flange F, having an annular groove, J, and notch K formed therein, of the clamp-ring G, provided with a stud, M, a screw, L, and with au upright arm, D, of the bearing E, and the spindle B, substantially as herein shown and described, and for the purpose set forth.
